中文摘要：
大型旋转机械的故障在发生或发展时，其运行过程具有明显非平稳特性的瞬态过程。结合Hilbert—Huang变换的特点，本文提出了运动能量Hilbert-Huang变换分析方法，它融合了转子同截面两通道的振动分量，能准确地反映转子发生故障时的瞬态过程运动能量的变化。工程实践应用表明：运动能量Hilbert—Huang变换分析对于旋转机械故障诊断是一种新的、较为实用的信息融合方法。
英文摘要：
When the faults of the large rotary machinery are happening or developing, the moving processes of the machinery are obviously transient processes. Based on the Hilbert-Huang transform, the Hilbert-Huang transform of kinetic energy was brought forward. It can fuse the vibration information of the two channels fixed at a section of the rotor and reflect exactly the change of the characteristic in the transient processes. Engineering practice indicates that the Hilbert-Huang transform of kinetic energy is a new and usable method for rotary machinery fault diagnosis.
